Combining like terms would be defined as multiplying each term in a set of parentheses by the number outside of the parentheses.
Answer:
5000
Step-by-step explanation:
Let x be the number of yearbooks to print and sell.
Each costs $7 = -7x
Sells for $35 = 35x
When business breaks even it means the total cost is equal to the total revenue. Hence:
35x - 7x = 14000
<=> 28x = 14000
<=> x = 5000
So at 5000 yearbooks , they seek before their business breaks even

7x + 43, that’s what I got
Part 1:
-3a+5(a-1)-7=
-3a+5a-5-7=
2a-11
Part 2:
a=-5
2(-5)-11=
-10-11=
-21
